white smoke pouring from exhaust

New guy here. I've been pouring through old posts, but couldn't find an answer so i figured it was time for my first post. First a little background on my bike... I purchased an 81 KZ650 CSR, which had the carbs and tank removed by the PO and according to him the bike ran when he first bought it, but quit running soon thereafter.

What i've done so far:
-checked valve clearances
-installed new plugs
-bought a "new" set of VM24 carbs (a mangled set of VM22's came in a box with the bike)
-checked float bowl settings on new carbs and installed with factory airbox & new filter
-drained ~7.5 quarts of oil from the bike (correct amount is 3.7 qts)!! filled to correct level w/ new filter

Next I attached a 3 foot section of fuel hose with inline filter and filled the carbs. After cranking for some time i finally got it started. The motor idled fine and the throttle response was good, but after 30-45 seconds white smoke started pouring out the r/h exhaust. I let it run for a minute before i was smoked out of my garage and had to shut it down. I started the bike again a few days later with the same result.

Could this smoke be from the excessive amount of oil that was in the bike? Could that much oil have ruined something in the engine?

What should I do next?

thanks in advance!

Sounds like the previous owner just kept pouring oil into the engine until it ran out of the filler cap hole. I would take the bike out and ride it. It may just have a bunch of oil pumped into the exhaust system and when the pipes get hot enough it starts smoking. Riding it may help blow it out. If it doesn't stop smoking after 5 or 10 miles do a compression check. Ed

ditto ed.just got a goldwing did the same thing.takes forever to burn it out.this is how i fixed mine ,dident want to wait for it to burn out lol. :evil:
